"The safety of players, club officials and match officials is paramount on or around the field of play, and this clear breach of security is a matter I will be discussing with SPL chief executive Neil Doncaster tomorrow."

Mr Doncaster said he was "shocked and appalled" by the incident.

He said the incident would be investigated thoroughly.

Celtic won the game 3-0 to ensure the SPL title race goes to the final day.

The incident occurred after their second goal, in the 49th minute.

The suppporter ran along the touchline towards Lennon and clearly made contact with the Celtic manager before being pushed to the ground by police and stewards, handcuffed and bundled out of the stadium.

Trouble then broke out in the Celtic section of the ground between fans and police.
